About this 3D model

My previous version ( v1.0 ) of key hoder was alright, but had some design flaws and mainly, since then, I discovered the allmighty threaded inserts. So the goal was clear - make the model from scratch, more design consistent and get rid of the nuts. The result is Swiss key holder 2.0 Print instructions Printed in PLA, but any material should do No supports needed 3MF and gcode are double color 30% infill 3 perimeters Ironing recommended Additional hardware needed 2x M3 threaded insert 2x M3 screw 10-20mm (depends on number of keys (M3x16 for 8 keys))
